Ceramic Replacement Blades - 10104 & 10408

Slice 10404 box cutter blades are compatible with Slice box cutters, pen knives, and the Slice Mini Cutter. These 100 percent zirconium oxide blades retain their edge 11 times longer than steel and feature our proprietary finger-friendly grind. Slice ceramic blades require no oil coating or special maintenance; they're non-sparking, non-magnetic, and never rust. The 10404 rounded tip offers extra protection against accidental puncture injuries. When you need a fresh edge, simply reverse the double-sided blade.
